Some of the 16 FALN prisoners offered clemency by President Clinton have vowed to return to violence once they are freed, according to tapes made by the U.S. Bureau of Prisons, it was reported today. At least some of the imprisoned Puerto Ricans nationalists were taped saying that “as soon as they get out of there [prison], they were going to return to violence,” the report in Newsweek quotes a law-enforcement official as saying. The still-secret audiotapes are the main reason the prisons bureau, which rarely gets involved in clemency decisions, strongly urged Clinton not to grant clemency to members of the group, it adds. The FALN is blamed for 130 bombings during the ’70s and ’80s. Mayor Giuliani, who has criticized the clemency offer, said it was now time for the president to admit he was wrong. “Rather than continuing to defend this, it would be in the best interest of the country if the president admitted this serious mistake and immediately rescinded the offer of clemency to these criminals,” Giuliani said. White House scandal spokesman Jim Kennedy declined any comment on the alleged tapes, but said Clinton got a “full range of views” before offering to commute the sentences of the FALN members. Clemency advocates say the 16 members of the FALN – whose Spanish acronym means Armed Forces of National Liberation – in question weren’t directly blamed for any deaths or injuries. Critics note that several of the lethal bombings remain unsolved. One of the FALN’s victims, former NYPD Detective Anthony Senft, said he was not surprised that members of the group still backed violence. Senft was among the police officers maimed in the FALN’s New Year’s Eve 1983 bombing of police headquarters, along with Rocco Pascarella and Salvatore Pastorella. Senft, partially blinded by the attack, said yesterday he “always believed they would reorganize and start killing again” if freed. “Terrorists are terrorists regardless of color, ethnicity or religion. How can the president let them out to hurt more innocent adults and children?” ‘What more do you need? Do you want us to make the bombs for them?” Senft asked incredulously. Senft said he hopes to address Congress this week to question the president’s decision – and demand an investigation into the process that led to the move. Kennedy said the members offered clemency – including Dylcia Pagan, wife of chief FALN bomber William Morales -“had all made statements disavowing their past actions.” The 16 haven’t publicly renounced violence yet, though the White House says it expects to hear “quite soon’ from their lawyers. All phone calls by federal prisoners are monitored except when they talk to their lawyers. All prisoners are warned of the tapings during orientation and notices are posted on all prison phones, prison officials say. Normally privacy laws bar release of the prison tapes but they can be subpoenaed and released by Congress. Sen. Paul Coverdell (R-Ga.), who chairs a terrorism subcommittee, will “likely” hold hearings, to determine precisely what information Clinton had when he decided to offer clemency – apparently over the objections of law-enforcement officials. But some Puerto Rican officials say Clinton didn’t go far enough – they say the FALN members are political prisoners and should have been offered clemency without the requirement of renouncing violence. Asked about the Newsweek report, Hillary spokesman Howard Wolfson said, ‘Her position has been throughout that the prisoners should not be released until they explicitly renounce violence.”
